PRB: WaitNamedPipe and Error 253 in Windows 95

SYMPTOMS

In Windows 95, when WaitNamedPipe fails due to an invalid pipe name passed as the first parameter, GetLastError returns error 253, which is not listed as a possible error code for this function. When you run the same code on Windows NT 4.0, the error code 161, ERROR_BAD_PATHNAME, appears.

RESOLUTION

To workaround the problem, you can resolve error 253 the same way as error 161, ERROR_BAD_PATHNAME. However, it has to be hard coded. For example:

   if ( !WaitNamedPipe(lpNamedPipeName, NMPWAIT_USE_DEFAULT_WAIT) )
      if (GetLastError() == 253)
         printf ("ERROR: WaitNamedPipe failed due to bad path name.");

STATUS

Microsoft is researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
